The leaked report comes as the mandate of Somalia's transitional federal government draws to an end next month. Somalia has been without a functioning government since 1991.

In this episode of Inside Story we ask: Who is responsible for corruption in Somalia? And is there even the political will for good governance in Somalia in the future?

Al Jazeera's invitation for a government representative to appear on the show was declined.

Joining presenter Laura Kyle to discuss these issues are guests: Peter de Clercq, the UN's deputy special representative for Somalia; Abdurahman Abdullahi Baadiyow, one of the leaders of the Islah Party, which is the Muslim Brotherhood in Somalia, and also a presidential candidate.

"Beyond the transitional period there are very concrete ideas on setting up a joint financial accountability mechanism that will ensure the flow of resources both from outside and from within are best used for the public's interest."

FINDINGS IN THE LEAKED UN REPORT:

Out of every $10 received by Somalia's transitional government between 2009 and 2010, seven dollars are unaccounted for.

Back in May the World Bank said $131m in government revenues were unaccounted for from that same period.

The UN report says almost a quarter of government spending in 2011 – or more than $12m – was what it calls "absorbed" by the office of the president, prime minister and the parliamentary speaker.

The report also says that a further $40m in government revenues in 2011 could be missing.
